Hi guys i take my bike from the mechanic and she run great :lick: :lick: she seems another bike!!!
i put on 150 main jet and bmc open filters on my mikuni............
the prblem is that around 5500 gm there is a sort of hole, as too much fuel ,and then she opens great...
mechanic says to me that is no airboxes the cause,what i can do??
in the next two weeks i have to do another carburation for the new exhaust,and i want to solve this problem.....
thanks and good run :D

Try to lower the needle one notch to lean it out in the mid range. The air box isn't critical and the engine will rune very well without it.
